Definitions

  • a working connection path provided for an active connection fiber and a geographically different routed replacement connection path provided for a redundant connection fiber are advantageously used for the transmission of optical signals, the one for the active connection fiber
  • the intended working connection path is routed via a first "star point” network node and the replacement connection path provided for the redundant connecting fiber is routed via a second "star point” network node.
  • the working connection path WP is formed from the second, first, ninth, tenth and eleventh connection path sections D2, D1, D9, D10, D11, the logical Working "connection WV is thus also routed via the first, third and fourth add-drop multiplexer ADM1,3,4, the first connection path section D1 having the first optical switching means DM1 of the first Star point "network node S1 is connected and is used several times as part of the working connection path WP.
